The volume of a cylinder (think about the volume of a can) is given by V = πr2h where r is the radius of the cylinder and h is the height of the cylinder. Suppose the volume of the can is 121 cubic centimeters.
a) Write h as a function of r.
Answer: h=V/[(pi)r^2]
c) What is the measurement of the height if the radius of the cylinder is 3 centimeters?
Answer: h=121/[(pi)3^2]
h=121/9(pi)= 4.2795 cm
